ROOFING.I

SPECIFICATION forming part of Letters Patent No. 522,330, dated July 3, 1894.

' Application filed April 29, 1893. sesamo. 472,387. v(No specimens.)

To all whom it 'may concerm,

RICH SCHULTZ, a subject of the German Emperor, residing at Hamburg, in the German Empire, have invented certain new anduseful Improvements in Roofing, of which the following is a specification. i v

My invention relates to improvements in that class of roofing which is known under the description of hardroong; and the object of this invention is to make the latter applicable for sloping roofs of every description, such as saddle, hipand dome shaped roofs as well as for iiat roofs, without necessitating any alteration in the system, in which are combined both the advantages of flexible and hard-roofing. v

Referring to the drawings which form a part of this specification, Figure l, is a perspective and Fig. 2, a sectional View of a flat roof containing my invention, while Fig. 3, is a sectional view of a somewhat modified construction of roofing.

In carrying out this invention the boardin g b of the framework of a roof, or the Monierof asphalted fabric or paper a and on this are laid metal strips d of angularcross section at a distance one from the other which corresponds with the breadth of the plates c to be employed as hard covering. The-metal strips d are fastened to the asphalted paper or fabric by pairs in such a manner that the upright legs of each pair of adjoined strips are touching one another. Y

The compartments thus formed by these strips are then covered by a layer c of mineral goudron or other suitable cement and on this is applied again a layer of asphalted paper or fabric 0,. The upper side of the latter is thereafter covered'by a layer of any suitable cement e', such as aforesaid, in which the cover-plates carefnally embedded. These v glass windows by a so-called cames. Finally,

' the joint between the two adjoined metal Be it known that I, JOHANN CARL HEIN strips d is Iilled out by means of a seam g of soft solderwhich may be smoothened thereafter.

Instead of a pair of angle-shaped metalstrips, a single strip of T -shaped cross-section maybe used, and in this ease that part of the web which projects beyond the cover plates should be longitudinally severed into two parts, in order to be bent over-in opposite directions on to the platescas above described. In tlhis case the solderjoint maybe dispensed wit Where it is desirable, to have the upper edges of the webs of the metal strips d flush with the cover-plates c, the adjoining edges of the latter maybe beveled and the upright anges of the metal strips bent so as to t the beveled'edges. The space between the two adjoining metal strips d is then filled with lsolder g, as heretofore mentioned, which may be made plane with the upper surface of the cover-plates, as illustrated by Fig. 3.

In some cases the layers a and e may be dispensed with, so that the cover-plates c may be (directly embedded'in the layer of 4mineral goudron or tar on the asphalted paper or fabric a, Without departing from the nature of this invention.

This system of roof-covering has the purpose to make the roof by the soft or exible bottom-layer water and air-tight and by the hard .cover-plates to insure strength and durability as well as protection against atmospheric and mechanical inuences, such as oc-V Having now described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A system ofiroofing comprising I-shaped i metallic strips extending from ridge to eaves and dividing the roof into fields of a width equal to that of the plates or sheets of roofing material employed, a foundation of cement in which the foot flange of said strips is em- IOO bedded and sheets or plates of rooting material embedded in said foundation and secured in position under and by the head flanges of the aforesaid strips, substantially `as and for the purpose set forth.

2. A system of roong comprising metallic angle strips arranged in pairs, as described, said strips extending from ridge to eaves and dividing the roof into fields of a width equal to that of the sheets or plates of rooting material employed, a foundation of cement in which the foot flange of said strips is embedded, sheets or plates of rooting material embedded in said foundation and secured in position by the bent over upper portion of the web of the strips, and a waterproof filler, as soft solder, filling the seam or space between two of said strips, substantially as and for the purpose set forth.

3. A system of roofing comprising a suit able bed, a Waterproof covering therefor, angle retaining strips secured thereto in pairs,

said strips extending from ridge to eaves and dividing the roof into fields of a Width equal to that of the rooting material employed, a layer of tar or similar cement applied to the Waterproof covering between the retaining strips, roofing sheets or plates embedded in said cement and having bearing on the foot of the retaining strips, said sheets or plates secured in position by the bent over edges of the vertical members of the strips, and a Waterproof filling for the seam between the retaining strips of each pair, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of Vtwo Witnesses, this 4th day of April, 1893.
